Gravity

Open Ended

Why is understanding gravity important in our daily lives and in the universe?

Multiple Choice

Based on the story of Newton and the apple, what is the 'unseen force' that attracts objects towards the Earth?

• Magnetism

• Friction

• Gravity

• Electricity

Open Ended

Explain how Newton's observation of the apple led to the discovery of gravity and describe why unbalanced forces are important in changing the motion of objects.

Open Ended

Describe how the concept of gravity connects the motion of the apple in Newton's story to the idea that all matter is affected by gravity.

Multiple Choice

Which of the following statements best describes the relationship between matter and gravity?

• Only living things are affected by gravity.

• Only objects with large mass are affected by gravity.

• All matter with mass is affected by gravity.

• Gravity only affects objects on Earth.

Multiple Choice

Why don’t we see objects being pulled towards one another in everyday life?

• Because the mass of most objects is too small to cause a noticeable attraction.

• Because gravity does not act on small objects.

• Because air resistance cancels out gravity.

• Because objects repel each other.

Open Ended

Explain how the Earth's gravity affects both the weather and the atmosphere.

Multiple Choice

According to the Law of Universal Gravitation, what two factors determine the size of the gravitational force between two objects?

• Mass of the objects and distance between them

• Volume of the objects and their color

• Temperature and pressure

• Shape and speed of the objects

Multiple Select

Which of the following statements are correct according to the Law of Universal Gravitation?

• Gravitational force increases as mass increases.

• Gravitational force decreases as distance increases.

• Gravitational force is not affected by mass.

• Gravitational force increases as distance increases.

Multiple Choice

What is the main difference between weight and mass as shown in the astronaut example?

• Weight changes depending on gravity, but mass stays the same.

• Mass changes depending on gravity, but weight stays the same.

• Both weight and mass change depending on gravity.

• Neither weight nor mass change depending on gravity.

Open Ended

Explain why you would still have some weight in space, even though gravity is very weak.

Multiple Select

Which of the following statements about objects in orbit are correct?

• An object in orbit is in free fall.

• Gravity is pulling the object toward the Earth.

• The object is moving at a constant speed forward.

• There are no forces acting on the object.

Multiple Choice

What two forces combine to create the curved path of an orbit?

• Gravitational force and forward velocity

• Friction and gravity

• Magnetism and inertia

• Air resistance and gravity

Open Ended

What questions do you still have about gravity or its role in orbiting objects after today's lesson?
